Application June 19, 1947, serial-No. 755,557

This invention relates to cap removers, vand more particularly to a device for opening receptacles of the type having a vacuum cap which must be pried therefrom, said receptacle and cap providing slightly separated exterior shouldersi-` which will admit a thin prying tool therebetween. One object of this invention is to provide a deviceof the above nature which includes means for Ilocating and rmly holding the device manually against the receptacle in proper positionE for the eicient operation of the prying cam.

Another object is--to provide a device of the above'nature which will require no clamps, en-

circling bands, or other means for securing the device to the receptacle.

l Another object ,is to provide a device of the above nature having a prying cam which is readily adjustable with relation to the locating means, whereby the device will operate efiicently to open receptacles of a wide range of sizes. I i fA further object is toprovide a device ofthe above nature which will be simple in construction, inexpensive to manufacture, easy to apply and manipulate, compact, ornamental in appearance, and very efficient and durable in use.

Withl these and other objects in View, there has been illustrated on the accompanying drawing one form in which the invention may conveniently be embodied in practice.

-In the drawings,

Fig. 1 is an oblique elevational view, showing the front and side of the improved pry-olf cap remover.

Fig. 2 is a cross section on the line 2-2 of Fig. 1, looking downwardly.

Fig. 3 is a plan view showing the flattened cam and a portion of the bit.

Fig.4 is an elevation showing the cap remover as it appears in the operation of removing a cap from a receptacle.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral I indicates an elongated vertical channel-shaped frame formed from sheet metal and comprising a. pair of divergent wings II, I2 extending integrally from opposite edges of a rectangular back I3.

The upper end of the back I3 is extended above the wings II, I2 and then rearwardly and downwardly to form an inverted U-shaped lug I4. A bit I5 in the form of a cylindrical rod is slidably and rotatably supported in a pair of aligned aperturesat. formed in the sides of the U-shaped lug I 4, andfretained therein by a dat key I1, secured,

5 claims. (ci. a1-3.36)

as by welding, to the rear end of the bit I5 said bit having a wide flattened forward cam I8 formed integrally with the front end thereof, which also assists in keeping the parts from separation. j p

The aligned apertures I6 in the lug I4 are so disposed as to hold the bit I5 slidably in a position bisecting the angle between the divergent wings I I, I2. The flattened cam I 8 may be made of any suitable proportions to lit under any pryoff cover cap commonly found on the market.

In one instance it has been found that a ca m three-eighths of an inch wide, and, one-sixteenth of an inch thick will operate satisfactorilyfolwr a wide range of bottle sizes. i

Operation In operation, the centralizing frame I0 willbe held manually in a vertical position against the side of the receptacle R which it is desired to open,

.in the position shown in Fig. 4. The divergent wings II, I2 will then serve to locate the-frame I 0 upon the side of a cylindrical or polygonal receptacle in a position substantially parallel to its ax1s.

The cam I8 will be then inserted into the narrow space between a shoulder I9 of the receptacle R and a projecting edge 20 of the cap C, by a sliding movement oi the bit I5 in the lug I4-the extent of said movement being dependent upon the relative diameter of the receptacle and the edge of the cap.

While the frame I0 is held against the receptacle R by one hand, the key I1 will be rotated by the other hand to turn the cam I8. The cam I8 will thus relieve the vacuum in the receptacle and effectively pry the cap therefrom-the parts then assuming theposition shown in dotted lines in Fig. 4, wherein the numeral I8' indicates the position of the cam, the numeral I9' indicates the position of the receptacle shoulder, and the numeral 20 indicates the position of the projecting edge of the cap C.

The width of the cam I8 preferably is such that when, it is disposed vertically, as shown in dotted lines in Fig. 4, the cap C will be raised to a position where it may be readily lifted from the receptacle R, and yet not raised sufficiently to permit said cap to slide accidentally ofE of said receptacle.

One advantage of the improved pry-off vacuum cap remover herein disclosed is that it will operate eiiiciently to remove caps of various sizes .from receptacles of diierent diameters.

Another` advantage is that it is not necessary to clamp the device upon the receptacle as it may be held in its operative position with one hand while the cam is operated with the other hand.

A further advantage is that the bit I5 is slidable so that application of the device may easily be made, inasmuch as the frame lil may be applied against the side of the receptacle while the cam is 'in retracted position, and the cam I8 then inserted into the narrow space between the shoulder I9 and the projecting edge 2i) of the cap C.

Another advantage is that the vdevice is small, light in weight, and may be readily manufactured without requiring any complicated forming `op-A erations or tools.

While there has been disclosed in this Specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and

that the invention is not to be limited to the I specio disclosure, but may rbe modified and embodied in various other forms without departing from its spirit. In short, the invention includes al1 the modifications and embodiments coming Within the scope of the following claims.

Having thus fully described the invention, what is claimed .as new, and for which it is desired to secure Letters Patent, is:

1. In a cap remover for cylindrical containers of `the type providing a narrow space 'between a shoulder on the container and the edge of its cap, a channel-shaped frame having spaced vertically .extending edges for engagement kwith the side of the vertically-held container, a cam mounted in said frame for rotation about an axis perpendicular to said edges, and a handle for rotating said cam. said handle including a bit sldable horizontally in said name and carrying said which said frame includes an upper outwardlyoffset extension of inverted U-shape provided with aligned apertures slidably and rotatably supporting said bit.

3. A cap remover for cylindrical containers of the type providing a narrow space between a shoulder on the container and the edge of its cap, an elongated vertically extending channelshaped centralizing frame, a horizontal bit, said frame having an aperture in the web portion thereof for rotatably and slidably supporting said bit at right angles to said web portion in substantially equidistant relation to the vertical side edges of said frame, said bit including a at end cam located on the concave side of said frame, and manual Operating means at the other side of said frame.

if el. The invention as dened in claim 3, in which said bit is slidable in said aperture, and said cam and said operating means are laterally enlarged whereby said bit will be retained in said aperture.

5. The invention as defined in claimv 3, in which the back of said frame is extended rearwardly and downwardly, and provided with an additional bit-supporting vaperture aligned with th aforesaid aperture. 's
